			<li>check results div below to see that before adding text, document is smaller than viewport
			<li>after adding text, document should be bigger than viewport,and check that viewport size hasn't changed,
				except maybe being a little bit smaller (about 15px) because of the size of the scrollbars
			<li>resize browser window and click the "recompute size" button; reported viewport size should change
			<li>scroll the window and click "recompute size" to see that the scroll position is taken into effect
